A consumer maximizes satisfaction by consuming 4 units of clothing (represented on the vertical axis of an indifference map) and 2 units of food (represented on the horizontal axis). If the price of food increases from $5 to $6, the price of clothing remains at $5 and the budget remains $30, the consumer will move to an indifference curve with a _________________________ level of satisfaction and the new marginal rate of substitution will be equal to _____________________________.
